Natural dyes
by Gwen Fereday  

OK, I am just starting to work on my 'natural dyes' information collection and I wanted to ask a brief question from those who may have already read/perused/drooled on this book. My college ILL librarian is telling me that this book may cost me $10-$20 to ILL - it is currently available *used* on abebook.com for around $14: So, is this reference material good enough that I should just buy it and be done with it?

*chuckle*

Mostly, I am concerned that it may not focus on historical dye processes that would be relevant to my 16th century German focus. Thank you in advance for your input!
